Dyeing liquid heating arrangement for dyeing machine

Abstract

The invention discloses a device for heating dyeing liquid used in a dyeing machine with heat conduction oil. The heating device includes a heat exchanger and a dye vat. The heat exchanger is composed of a cylindrical shell, a tube sheet and several heat exchange tubes. Its structural feature is that it is also equipped with an oil boiler. The oil outlet of the oil boiler is connected with the inlet on the cylindrical shell of the heat exchanger through the oil pump, oil inlet valve and oil pipe, and the outlet on the cylindrical shell is connected through the oil outlet valve and the oil pipe. The oil pipe communicates with the oil inlet of the oil boiler, so that a closed circulating oil circuit is formed between the oil boiler and the cylindrical shell. The dyeing liquid flowing through the heat exchange tube is heated by the heat conduction oil entering the cylindrical shell. Using the dyeing liquid heating device for the dyeing machine to heat the dyeing liquid can not only save energy, reduce the use cost, but also prolong the service life of the equipment.

Description

(1) Technical field [0001] The invention relates to a heating device. Specifically, it is a heating device that uses heat transfer oil to heat the dyeing liquid used on the dyeing machine. It is suitable for heating the dyeing solution in the printing and dyeing industry. (2) Background technology [0002] At present, in the printing and dyeing industry, the heaters used to heat the dyeing solution are steam heaters. This steam heater contains a heat exchanger, which is composed of a cylindrical shell, a tube sheet and several heat exchange tubes. The two ends of the cylindrical shell have a medium inlet and a medium outlet respectively. Said tube sheet and heat exchange tubes are located in the cylindrical shell. Among them, there are two tube plates, and they respectively leave a space between the two ends of the inner cavity of the cylindrical shell, and their surroundings are sealed with the inner wall of the cylindrical shell, and a number of through holes are corre...

AI Technical Summary

Problems solved by technology

The large temperature difference will cause destructive factors such as impact on the equipment, thereby shortening the service life of the equipment;

[0004] The 2nd, because the steam that enters cylindrical casing is directly discharged from the outlet of cylindrical casing in vain after heating the heat exchange tube, it can only be used once, not only the utilization rate of heat is low (usually only about 35%) , and a serious waste of water resources;

[0005] The third is waste of energy and high cost of use
